Passive dust control system

摘要

A system for providing passive dust control for a transfer of bulk material from a first station to a second station in a material handling system. A dust containment housing encloses a first station and a second station. Bulk material is transferred from the first station to the second station inside the dust containment housing. A region of low pressure inside the dust containment housing is defined by a circulation compartment. Air carrying suspended particles of bulk material flows from a region of high air pressure generated by the transfer of bulk material to the region of low air pressure. The suspended particles of bulk material either remain suspended in the air inside the housing or settle out of the air into the bulk material inside the housing.
